Application filed June 30, 1906. Serial No. 324,177.

To all whom it may eon/corn.-

Be it known that I, ROBERT DAVID BAKER, a citizen of the United States, and a resident of Las Vegas, in the county of Lincoln and State of Nevada, have made a new and useful Improvement in NutLocks, of which the following is a specification.

My invention is an improvement in nut locks, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1. is a partial longitudinal section of the improvement on the line of the groove in the bolt. Fig. 2 is a perspective view of the bolt. Fig. 3 is aperspective view of the nut, and Fig. 4 is a side view of the look.

In the present embodiment of my invention, the bolt A, having the head a, is provided at its threaded end a, with a longitudinal groove M, the said groove extending a short distance beyond the threaded portion of the bolt.

The nut B, may be of any suitable shape, in the present instance square, and is provided upon two of its opposite faces with grooves b, b, the said grooves being transversely of the bolt when the nut is in place thereon.

The lock proper C, is composed of a piece of rod or wire of suitable cross section, and one endcof the rod or wire is adapted to engage the groove in the bolt, the outer face of the said end being cut away as at 0 whereby to not interfere with the threads of the nut, that is, that portion of the rod which extends above the level of the bottom of the threads of the bolt is cut away. The length of cut away portion is equal to approximately the thickness of the nut, and the rod or wire extends straight a short distance as at c and is then bent over and upwardly and laterally as at a the extreme end of the wire 0 being bent transversely of the portion 0, whereby to lie in one of the grooves b of the nut.

In operation the nut is turned upon the bolt the required distance. The end of the lock 0 is then inserted in the longitudinal groove 0, of the bolt, until the shoulder a at the end of the cut away portion a, is in engagement with the outer face of the nut, at which point the transverse end a of the lock will be in engagement with one of the grooves 11, b of the nut.

It will be evident from the description, that the transverse end 0 of the lock will prevent rotation of the nut, and that the engagement of said transverse end with the groove 1), or b, will prevent removal of the lock, unless some considerable traction is exerted upon the looped portion thereof.

It will be understood that the wire or rod is possessed of some degree of resiliency which will permit the transverse end 0 to spring outwardly a suiiicient distance to disengage it from the groove when it is desired to remove the look.

I claim 1. The combination with a bolt having a longitudinal groove at the threaded end thereof, and a nut having a groove on opposite faces thereof, and transversely with respect to the bolt, of a rod or wire having one end in the groove of the bolt, said end being cut away on one side to permit the passage of the nut, and provided with a shoulder at the end of the cut away portion for engaging the outer face of the nut whereby to limit the inward movement of the rod, the other end of the lock being bent upwardly and outwardly, and transversely whereby to lie in one of the grooves of the nut, when the shoulder is in engagement with the outer face of said nut.

2. The combination with a bolt having a longitudinal groove at the threaded end thereof, and a nut having a groove on the face thereof and transversely with respect to the bolt, of a rod or wire having one end in the groove of the bolt, and provided with a shoulder for engaging the outer face of the nut whereby to limit the inward movement of the rod, the other end of the rod being bent whereby to lie in the groove of the nut when the shoulder is in engagement with the outer face of said nut.

ROBERT DAVID BAKER.
